Orange Is the New Black (sometimes abbreviated to OITNB) is an American comedy-drama television series created by Jenji Kohan for Netflix. The series is based on Piper Kerman's memoir Orange Is the New Black: My Year in a Women's Prison (2010), about her experiences at FCI Danbury, a minimum security federal prison. Produced by Tilted Productions in association with Lionsgate Television, Orange Is the New Black premiered on Netflix on July 11, 2013. Its seventh and final season was released on July 26, 2019.

As of 2016, Orange Is the New Black was Netflix's most-watched as well as its longest-running original series. It was widely acclaimed throughout its run and received many accolades. For its first season, the series garnered 12 Emmy Award nominations, including Outstanding Comedy Series, Outstanding Writing for a Comedy Series, and Outstanding Directing for a Comedy Series, winning three.

A new Emmy rule in 2015 forced the series to change categories from comedy to drama. For its second season, it received four Emmy nominations, including Outstanding Drama Series, and Uzo Aduba won for Outstanding Supporting Actress in a Drama Series. Orange Is the New Black is the first series to score Emmy nominations in both comedy and drama categories. The series also received six Golden Globe Award nominations, six Writers Guild of America Award nominations, a Producers Guild of America Award, an American Film Institute Award, and a Peabody Award.
